I. Company Profile
Shanghai JIN DUN Industrial Co., Ltd was founded in 2013 and is located in
Shanghai. With senior American scientists as the core and a team of
internationally renowned experts as advisors, the company has gathered industry
elites to lead the R&D innovation in medicinal chemistry, focusing on the
technological development and industrialization of high-end generic drugs, high
value-added drug intermediates, and new tumor diagnostic reagents.

II. Clopidogrel series intermediates product introduction
Clopidogrel, Prasugrel and Ticlopidine are antithrombotic drugs.
Clopidogrel is a super heavyweight drug, with global sales exceeding USD 10
billion in 2010. After the patent of clopidogrel expired in 2012, the market
share further increased. Prasugrel and ticlopidine, both important complementary
brands in the antithrombotic market, also have annual sales of more than $1
billion.
All three drugs are manufactured with 2-(2-Thienyl)ethanol (structure I),
or 2-(2-Thienyl)ethylamine (structure II), or tetrahydrothieno[3,2-c]pyridine
(structure III) as key ingredients. (structure III) as key ingredients.
The company has successfully developed a new production process for the
above mentioned series of intermediates: 2-thiopheneethanol,
2-thiopheneethylamine and tetrahydrothieno[3,2-c]pyridine for this heavy drug
market. Compared with the traditional process in the market, the new process has
completely different raw materials, shorter process route, higher yield and
lowest cost, and has absolute advantages over other production technologies,
with good prospects for industrialization. The main features of the process
route are:
(i) Lowest cost. After adopting the modified process, the production cost
of the product is reduced by about 20% compared with the traditional process,
and the gross margin of the product can reach 40%.
(2) Excellent quality. The product "2-thiopheneethanol" produced by the
modified process does not contain the key isomeric impurity
"3-thiopheneethanol", which is inevitably produced by the traditional process,
and the quality is significantly improved.
(3) Less pressure on environmental protection. Under the pressure of the
new environmental protection policy, the environmental pressure on the
industrialization of the new process is minimal.
(iv) The process is mature and feasible. At present, this type of process
has been verified by the plant scaling up production (110kg at one feeding), and
the process is mature and stable.
At present, the domestic core suppliers of this series of intermediates are
mainly one enterprise each in Zhejiang and Shandong. Due to the influence of
traditional process and environmental protection policy, Shandong enterprises
have basically stopped the production of this series of products, the market is
in short supply, the current market price of "2-thiopheneethanol" is about
110,000 yuan / ton, the price is expected to go up.
III. Other generic drug projects
At present, the company has completed the following generic drug process
technology research, if interested, we can discuss cooperation or technology
transfer.
1、The synthesis process and quality research of moxifloxacin, a super
broad-spectrum antibacterial fluoroquinolone drug.
2, Synthesis process and quality research of non-addictive analgesic
flupirtine maleate.
3, process development and quality study of esomeprazole sodium, an
efficient and safe anti-gastrointestinal ulcer drug.
4, synthesis process and quality study of safe and efficient
sedative-hypnotic agent phosphoprotol sodium.
5. Synthesis process and quality study of prasugrel hydrochloride for the
treatment of angina pectoris and coronary syndrome.
6、Synthesis process and quality study of ceftazidime, a semi-synthetic
broad-spectrum antimicrobial agent.
7、Synthetic process of lipid-lowering drug Clifedet.
8, Synthesis process of tolvaptan, the drug of choice for the treatment of
low blood sodium.
9, Synthesis process of the drug Rexagiline for the treatment of
Parkinson's disease.
2-bromo-2-(2-fluorophenyl)-1-cyclopropylethanone is used as the intermediate of Prasugrel.
Prasugrel is a thiophenopyridine antiplatelet developed by Eli Lilly and daiichisankyo, a Japanese pharmaceutical manufacturer. It is a precursor drug. It forms an active molecule after metabolism through cytochrome P450 in the liver and combines with platelet P2Y12 receptor to exert an active against platelet aggregation. Clinical studies have proved that 60 mg dose has better anticoagulant effect than 300 mg standard dose and 600 mg increased dose of clopidogrel, which can reduce the comprehensive risk of heart attack, stroke and death due to heart disease by 20%, and has fast effect, good curative effect, good drug resistance and bioavailability, and low toxicity.
